S Sandustry Tips
First factory

Build a stable first factory before you build a big one

Recommended approach: keep the opening Gold line compact, make each material path visible, leave open space under the Shakers for Gold, and give Residue its own exit before adding more production.

The Shaker, Wet Sand, and Water rules are official. The arrangement below is a readable starter layout, not a promise that every map should use the same final shape.

Build in this order

  1. Choose one controlled input

    Feed a manageable Wet Sand stream instead of flooding the entire area. A smaller input makes it much easier to see whether the bottleneck is Water, Shaker capacity, or Residue movement.

  2. Give Gold a clean drop zone

    Gold passes through the Shaker body, so the space below should stay open and separate from other solids.

  3. Give Residue a side exit

    Residue stays on top and moves slowly. Do not let it accumulate where new Wet Sand is entering.

  4. Keep Water mixing upstream

    Make Wet Sand before the Shaker area. Water is easier to diagnose when it has a clear basin/mixing zone rather than leaking through the production line.

  5. Scale only after each path is readable

    Add more Shaker capacity when you know which material is backing up. Expanding before that point often hides the real cause.

What “stable” means here

Wet Sand reaches the Shakers consistently.
Gold has an unobstructed collection area.
Residue can leave without burying fresh input.
Water loss can be seen and corrected upstream.

When the first factory is done

Stop expanding when the first loop is readable, not when it is large. A finished first factory is one where you can point to the Sand source, Water contact point, Wet Sand route, Shaker body, Gold drop space and Residue exit without guessing.

One small input change creates a visible downstream change.
A short stoppage can be traced to one stage instead of the whole layout.
Gold and Residue leave in different directions.
The next upgrade target is obvious before more machines are added.

Common first-factory traps

One shared pile for everything

If input, output and byproduct all meet in one pile, a stopped line becomes hard to read. Separate paths before scaling.

Water routed through the machine area

Water behavior belongs upstream. Keep the wetting step visible before Wet Sand reaches the Shakers.

No manual access

Early factories still need occasional clearing. Leave enough space to remove a trapped solid or watch the failing tile.

Scaling a hidden bottleneck

If you cannot name the constraint, adding machines usually hides it. Stabilize one cell first.

Upgrade path

This opening shape is a learning layout, not a destination. A good point to extend it is when you can name the real bottleneck from watching the factory, because that is the moment adding Shaker capacity stops being a guess.

  • Add more Shaker capacity when Wet Sand still arrives steadily but the Gold collection area fills slowly.
  • If a new unlock changes how Water or Wet Sand reaches the line, rebuild only the upstream mixing zone and keep the Gold drop area and the Residue exit separate.
  • When the layout becomes too compact to see the middle, rebuild wider around the Gold Factory staircase instead of cramming in more machines.
  • If Water loss is the recurring failure, fix it at the Water mechanics level before scaling the line.

Use the Gold factory diagram

Once this shape makes sense, the Gold Blueprint page zooms in on the Shaker staircase and its failure points.

Core takeaway

A first factory is easier to learn and debug when Wet Sand input, Gold output, Residue exit, and Water mixing stay visibly separated.

Use this as a starter shape

The layout here is for a readable opening loop, not a final factory footprint or a promise about exact throughput on every map.

Featured Questions

What should a first factory in Sandustry prioritize?

Readable material paths: controlled Wet Sand input, open Gold drop space, a separate Residue exit, and upstream Water mixing you can inspect.

When is a first factory ready to scale?

When one loop runs long enough that you can name the real bottleneck from observation instead of guessing based on overall mess.

Why is separation more important than compactness at first?

Because compact but tangled layouts hide failure points. Separation keeps input, output, and byproduct readable when the line stalls.
